-Would it be possible to get a significant muscular hypertrophy while eating paleo?? If so, could a bodybuilder (or any other sport practitioner in which weight could suppose any benefit) get on competition shape by eating an strict paleo diet??

I know the hypertrophy levels required by those kind of sports are not "natural" and that in a human evolutionary context they would have never been achieved. Logically, the amounts of food needed to keep "an overweight" state would be enormous and the specificity of it would surely work against the real needs of any hunter-gatherer.

I'm afraid is not so simple... First of all, any competitive bodybuilder has a pre-competition calorie intake of 4000 kcal or more... Of course, many of those calories come from supplements...
Moreover, glycogen storage in the muscle pulls water in, volumazing it and getting a fuller and harder appearance. (just what any bodybuilder aims for...) Thats why many bodybuilders rely on 30-50% of their calorie intake from carbs...

There is no reason you could not compete as an athlete while doing paleo. For a sport that requires a little more anerobic activity like hockey, sprinting, bodybuilding etc you would need a little more carbohydrate than what would be considered normal. Some sports that require over 5000 cal like rowing may be a little more difficult to cram enough whole foods down your throat but it can be done. It would be even easier if you allowed dairy...
